Shifty Ciliates Frequent Programmed Translational Frameshifting in Euplotids
Recent work suggests that there is a high frequency of programmed +1 translational frameshifting in ciliates of the Euplotes genus. Frequent frameshifting may have been potentiated by stop codon reassignment, which is also a feature of this group.
متن کاملShifty Operators in Changing Contexts
It 's fair to say that the study of indexicality has been primarily occupied with an swering one question: Why are certain elements I, you, yesterday opaque to modal quantification? Indeed, Kaplan ( 1977), the most celebrated theory of index icality, is designed precisely to answer this question: indexicals are rigidly speci fied once the character of a sentence is applied to the utterance c...
متن کاملEpigenetics of ciliates.
Research using ciliates revealed early examples of epigenetic phenomena and continues to provide novel findings. These protozoans maintain separate germline and somatic nuclei that carry transcriptionally silent and active genomes, respectively. Examining the differences in chromatin within distinct nuclei of Tetrahymena identified histone variants and established that transcriptional regulator...
متن کاملCommentary: Soda taxes, obesity, and the shifty behavior of consumers.
Rising obesity is a threat to public health, and taxing sugar-sweetened beverages (SSBs) in order to reduce consumption and thus caloric intake could be a viable policy response. But raising the price of SSB calories will raise the quantity demanded of relatively cheaper calories, and net effect on obesity is unclear. I review the evidence on shifting calorie demand and discuss the viability of...
متن کاملBacterial genomics: The controlled chaos of shifty pathogens
One of the great promises of genomics is that advances in the fight against infectious disease should be facilitated by knowledge of the complete genomes of human pathogens. We now know the genome sequences of a large number of bacterial pathogens, and these sequences are not only providing information to combat disease, but also providing interesting insights into the unique biology of pathoge...
